There are others!

Given the accent in the play, it could well be "verrue choux", or something like "warty" or "poxy cabbage", with all the quaint rusticity that cabbage entails. An English contemporary equivalent might be something like "poxwort" or "poxwurzel" even! Don't forget to Rrrroll the Rrrr.

I doubt there is a modern-day equivalent or even that the word ever existed, so it's up to your imagination, I imagine.
